liquid (water) and gas (air)
Shaving foam is an example of foam. It is a lightweight, frothy substance that is used to help lubricate the skin during shaving. Shaving foam is made up of tiny air bubbles dispersed in a liquid solution.
Aqueous film-forming foam (AFFF) is typically made from a mixture of fluorosurfactants, hydrocarbon surfactants, solvents, and water. These ingredients work together to create a foam that is effective at extinguishing flammable liquid fires by forming a blanket that suppresses the release of flammable vapors and cools the fuel surface.
The foam of the sea is a mixture, as is seawater itself. The foam differs from the seawater by containing dispersed as well as dissolved air. The dispersed air forms the bubbles of the foam.
There is more than one kind of foam. Styrofoam is a solid mixed with gas. Soap suds are made of a liquid mixed with gas. I would call foam, in technical terms, a composite material. It's made of more than one thing.
A few things make beach foam. First we need a breaking wave or other kind of agitated water. Then...: Soap spilled overboard will certainly do this. However, proteins washed off kelp beds also cause foam to form up.
aqueous film forming foam (AFFF), if you have one, although CO2 or dry-chemical fire extinguishers are also rated for combustible liquids, such as diesel.
AFFF is Aqueous Film Forming Foam
Foam is a substance that consists of two states of matter: a gas and a liquid or solid. The liquid or solid traps the gas inside.
No. I forbid it!
Foam soap is a liquid that has been aerated to create a foam. Therefore, the state of matter for foam soap is liquid.
Yes it is.
AFFF stands for Aqueous Film-Forming Foam. It is a type of firefighting foam used to suppress fires by creating a film on the fuel surface, preventing the release of flammable vapors. AFFF is commonly used for combating fires involving flammable liquids, such as gasoline or jet fuel.
AFFF- Aqueous Film Forming Foam
In order to produce foam, several things are required. First, the surface area needs to be increased. Soap bubbles are a type of foam, for instance. The surface area is increased by applying force. Next, certain reactive chemicals are required. In the case of soap bubbles, soap is required. There are many different types of foam, such as styrofoam, all requiring different levels of force and substances. Sea foam is another type of foam.
AFFF or aqueous fire fighting foam is a chemical agent that is added to water usually at a rate of about 300:1 (300gal water for 1gal foam concentrate) this mixture is then mixed with the outside air as it exits the nozzle and creates a blanket of foam that suffocates the fire.

There is no true 'gas' that is used to create the foam used to help extinguish any flammable liquids/metals that we run into. Most often you'll see AFFF (Aqueous Film Forming Foam) is the main foam that is used in most car fires or any flammable liquid fires. The foam is a concentrate, which can easily be compared to car wash soap. A small concentrate (usually from 3-6%) is used to create the foam blanket and eventually diminishing any air that the fire is using as fuel. All in all, it's not a gas, but more like car wash soap concentrate...that's the easiest way to compare it.
